Z'ea whom z5 may omwerm l lie it known that We, HENRY l "ZO HOUSE andHENRY' ALONZO HOUSE, .l eebanical engineers, both citizens OE the'United States 5 of Ainerloa and both teinporai 'esiding at Teddlngton,county of Surrey, england, but usually of Bridgeport, county oflairlield, and State of Conneetieut, United States of America, haveinvented a certain ne .r improved Feed llater am. @las liep@ i.egnlatoig of which the following is a speci tion. ln tubnlona steam.boilers or oerators in which the quantity of Water oer. i, Aed in themis comparatively small it is extremely important to main etant as i .inthe levelof the water as con e and to reduce or extinguish the level.falls below a For this purpose we employ an 1 d water and gas supplyregulaid shown in. Figures l, 2, 3 and i llie Hineaed drawings, in whichverlieal section taken on line il va sectional elevation e of Fig.1;*lfig. 8 a sectional pian lalroi'l. en line 3-3 of Fig. l, and Fig. ilshoe ille same apparatus to a smaller scale to a tubnlous boiler orgenerator v vessel ifi, ei any suitable shape is pro- @ed al; the Waterlevel of the Jr. '.lhe upper end of this ves- 1 eoted a pipe with thesteam oe U ei the boiler and the-lower end therea pipe il? with thelowelf'ert of the water'sease lil so the there is an equilibrium ofisere in, the vessel ll and in the boiler,

This plunger or piston operates theregulating tap or valve lli. ef the aas burners by which the boiler' isheated. ll' noer the water level falls, the 5 5 float S falls also, andlowers the slide Valve .U,j uncovering the upper part V; steam thenpasses by pipe V2 from the vessel R to the feed pomp and` sets it inniotioin and feed Water is introduced into the boiler or genera- 6o ter;but if from any cause the feed pump fails testari., or fails to forceWater into the boiler, and the Water level falls still lower, the floatS falls withv it and the valve U is lowered still farther whereby thelower port V' is iineov- 6 5 ered and steam passes by the pipe V3 to theAcylinder W', acts upon the plunger or piston W therein and in'oves itforward against the Opposing spriugW2 or weigl1t and causes it Y to shutthe gas tap or valve X thereby cutting 7o Off more or less completelygas from the burners and preventingthe generation of an y more steamvuntil the defect has been reine` died. When the water level rises againthe float S rises also carrying with it the slide 75 valve U whichcloses the lower steam port V' shutting off steam from t-he aforesaidcylinder 'W' the plunger or pistn in which is then pressed back by itsspring or weight and opens the gas valve X allowing the evapora- So tionto proceed. The steam behind the'pluir ger or piston 'W s allowed toescape, when the port V is closed,through a weeping hole 'or properlyadjusted tap V, On the other hand if the water level rises too high thefloat S5 S rises still higher taking with it the slide ValvegU Wliiehthen closes the upper steam port V, thereby stopping the feed pump andconsequently the further delivery oi food Water to the boiler. The portthrough the 9o slide valve U corresponding to the port V is made widerthan the port through the Valve U corresponding to the port V in orderthat the pori Vmay romain Open however 10W the float may descend in thevessel ll, and until 9 5 tliexproper level of Water has been restored intbesaid vessel. '.lle `lloat S may be guided in its op and downmovements by the pivoted arms Y or otherwise, and more or less of itsweight may be counterbalaneed if required by a spring S.

We clai'ml The new or improved apparatus for maintaining the level ofthe water in boilers or 'generators and for regulating the supply oflgas for heating the same which consists of a -closed chamber connectedwith the boiler or generator, two steam ports, one leading to a selfstarting feed pump, and the othei` to an apparatus for regulating thesupply of gas to the gas burners in the furnace of the b'oiler 1 orgenerator, a slide valve governing the said two steam ports and a iioatfor actuating the 15 said slide valve, combined,arranged and operatingsubstantially as hereinbefore described.

In witness whereof we have hereunto set vour hands in presence of twowitnesses.
